Answer:

Biologists at th Environmental Protection Agency

Answer:

The correct answer is - organ level organization.

Explanation:

The heart is made up of various types of tissues that include muscle tissue, nerve tissue, and blood tissue. All these types of tissues are organized to form the organ level organization which makes the heart is an organ.

Tissues are made up of cells and organs are made up of tissues and various organs combine together to do a specific function, this is an example of an organ system.

Thus, the correct answer is - organ level organization.

Answer:

Cells without lysosomal enzymes will not be able to digest food and these will lead to accumulation of wastes in the cells, leading to cancerous growth and the cells will not be able to live long.

Explanation:

Lysosomes is a membrane bound organelles found in eukaryotic cells that produce lysosomal enzymes which help to breakdown or engulfs biomolecules like proteins, carbohydrates, nucleic acids, lipids it engulfs in the cells to molecules it will easily be absorbed.

Without these enzymes or defect in these enzymes, biomolecules will not be broken down and it's resultant effect is accumulation of wastes which can lead to cells destruction.

Answer:

The structure that is not a part of endomembrane system is chloroplast. The correct option is B.

The endomembrane system is a membranous component system. The membranes of the nucleus, the endoplasmic reticulum, the Golgi apparatus, lysosomes, endosomes, vesicles, and the plasma membrane are all part of it. It doesn't include mitochondrial chloroplast membranes.

The endomembrane system is a network of membranes in the cell that serve to reconfigure, transfer, and bundle proteins and lipids.

The endomembrane system is a collection of eukaryotic biological membranes and organelles that work with each other to modify, package, and transport lipids and proteins.

Thus, the correct option is B.

Answer:

All energy on Earth originally comes from the Sun. Plants use sunlight in a process called photosynthesis, to make their own food and provide energy.  This is why plants are producers, because they make their own food. Cows eat plants, namely grass. So, when the cow eats the grass, the energy from the grass transfers to the cow. This is why cows are consumers, because instead of making their own food, cows, like humans, must consume their food to survive.

Answer:

The order of polarity from most polar to least polar is as follows:

O-H > N-H > C-H

Explanation:

The polarity of a substance is a function of the charges of the ionic elements that makes up the substance. A bond between two ions is considered polar if it is between a negatively charged and positively charged ions. Hence, the stronger the charges of the ions in the bond, the more the polarity.

In this question, hydrogen is said to form covalent bonds with carbon, oxygen and nitrogen in biological molecules. However, the covalent bonds formed will not possess the same degree of polarity.

The bond between oxygen and hydrogen (O-H) is considered most polar amongst these three because OXYGEN atom is the most electronegative among the three ions. Hence, it will pull more electrons to itself and make the hydrogen ion more electropositive. This is followed by the bond between nitrogen and hydrogen (N-H) because nitrogen is more electronegative than carbon. The least polar is the bond between carbon and hydrogen as carbon is the least electronegative, hence, will not be able to pull electrons from hydrogen effectively.

The order from most polar to least polar is: O-H > N-H > C-H

Answer:

its c) condensation and evaporation

Explanation:

Evaporation and transpiration are the two processes that allow water to enter the atmosphere. The correct option is A.

Transpiration is the method by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and water from the stem and roots moves upwards or is started to pull into the leaves.

The direct impact of transpiration is that it regulates plant temperature and provides water for photosynthesis. It also transports nutrients and sugars through the plant's vascular tissues.

Evaporation is a way of vaporization that occurs on the surface of a liquid as it transitions from the liquid phase to the gas phase.

Both of these process aids to enter water into the atmosphere.

Thus, the correct option is A.

Cells regulate chemical reactions through the use of proteins called enzymes, which are biological catalysts that help overcome activation 

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

In order to calculate the percentage decline over the period of time between 1979 and 2007, the general formula for percentage change will be applied. This is as follows:

[tex]\frac{B-A}{A} \times 100[/tex]

where:

A = final value

B = initial value

In this problem:

A = Initial population = 1,300,000

B = Final population = 640,000

Applying this formula to the problem, the percentage change in population between 1979 and 2007 is as follows:

[tex]\frac{B-A}{A} \times 100\\\\\frac{640,000 - 1,300,000}{640,000} \times 100 \\\\\frac{-660,000}{1,300,000} \times 100\\\\= \frac{-66,000,000}{1,300,000} \\\\= -50.769 \%\\= 50.77\% \\Note\ that\ the\ minus\ sign\ denotes\ a\ decline.[/tex]

B: The change in range over this period of time is the difference between the final population and the initial populations, which is calcalated thus:

B - A (as explained above)

= 640,000 - 1,300,000 = - 660,000 (the minus sign still shows a decline)

While the percentage shows a "relative change" in terms of percentage, the change in range shows an absolute or actual change.

Answer:

there is only one surface in which we can run off in rainy season and that is room

Explanation:

steffie matt

Answer:

On a sloped parking lot

Explanation:

Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil. The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

Fun Fact - Locusts are actually species of short-horned grasshoppers, they often gather in large swarms and can destroy entire fields of crops, because a single grasshopper can eat half its body weight in plants per day.

There are four trophic levels in the given food chain, i.e., producer, primary consumer, secondary consumer, and tertiary consumer.

A food chain is a network of connections in a food web that begins with producer organisms and ends with a predator, detritivore, or decomposer species.

In the given food chain, grass is produces, grasshopper is primary consumer, frog is secondary consumer, while snake is tertiary consumer.

Thus, there are four trophic levels in the given food chain.
